Rations and water were given adlibitum. The trial period lasts for 30 days. Test performed to determine differences in Duncan.
The results showed the addition of up to 5% starfruit into the ration does not affect the performance of chicken and chicken carcass weight parts. The highest value of income over feed cost was achieved by treatment with the addition of 0.5% ration starfruit juice.
